Description

薄片类介质分离机构及薄片类介质处理装置 技术领域
本公开涉及介质分离领域，例如涉及一种薄片类介质分离机构及薄片类介质处理装置。
背景技术
相关技术中的薄片类介质处理装置，如纸币清分机、扫描仪、点钞机等为了实现多张薄片类介质的批量处理，往往设置薄片类介质分离机构，用于将一摞薄片类介质，如纸张、钞票、卡片等薄片类介质(为描述方便以下将薄片类介质简称为介质)一张一张地依次送入薄片类介质处理装置内部。
如图1所示，相关技术中的薄片类介质分离机构包括机架、至少一组输送辊1′、固定辊2′、浮动辊3′及驱动组件，其中，输送辊1′和固定辊2′分别通过第一转轴4′和第二转轴5′支撑在机架上，浮动辊3′通过第三转轴6′支撑在机架上，浮动辊3′与固定辊2′相对设置；驱动组件包括用于驱动输送辊1′和固定辊2′转动的第一驱动组件和用于驱动浮动辊3′转动的第二驱动组件，其中，第一驱动组件包括电机7′和同步齿形带8′，分别与第一转轴4′和第二转轴5′传动连接，可以驱动第一转轴4′、第二转轴5′沿进纸方向转动，第二驱动组件(图中未示出)用于驱动第三转轴6′沿退纸方向转动。当固定辊2′与浮动辊3′之间存在多张介质时，固定辊2′驱动与固定辊2′接触的介质向下游输送，浮动辊3′驱动与浮动辊3′接触的介质向上游输送，因此只有与固定辊2′直接接触的介质才能向下游输送，从而实现介质的分离。

具体实施方式
在不冲突的情况下，以下实施例和实施例中的特征可以相互组合。下面结合附图并通过具体实施方式说明实施例的技术方案。
申请人发现，由于不同类型的介质表面摩擦系数不同，要实现不同类型的介质的分离所需要的摩擦力大小不同，通常介质越厚或者介质的表面越光滑，分离所需的摩擦力越大。图1所示的相关技术中的薄片类介质分离机构由于固定辊2′和浮动辊3′两者的相对位置固定，两者之间的压力保持不变，固定辊2′与介质之间，以及浮动辊3′与介质之间的摩擦力保持不变，在分离不同类型的介质时，容易出现介质分离失败的问题。因此，相关技术中的薄片类介质分离机构不能适应分离不同类型的介质的需求，对介质的适应性较差。
如图2至7所示，本实施例提供一种薄片类介质分离机构，包括机架1、分离组件2和调节组件3，分离组件2包括设置在机架1的输送通道110的高度方向两侧的固定辊21和浮动辊组件22，浮动辊组件22包括浮动辊222，固定辊 21和浮动辊222相对设置，浮动辊组件22活动地设置在机架1内，可沿输送通道110的高度方向移动，调节组件3抵接在浮动辊组件22上，调节组件3用于调节浮动辊222施加在固定辊21上的压力。
如图2所示，机架1包括第一通道板11、第二通道板12，以及两个侧壁13，其中，两个侧壁13相互平行且间隔设置，两者之间的宽度大于等于介质的宽度；第一通道板11和第二通道板12连接在两个侧壁13之间并分别与两个侧壁13垂直，第一通道板11和第二通道板12相对设置且间隔预定距离，形成介质的输送通道110，其中，两个侧壁13之间的距离为输送通道110的宽度，第一通道板11和第二通道板12之间的距离为输送通道110的高度，输送通道110的长度沿介质输送方向延伸。
分离组件2用于将单张介质从多张介质中分离出来，并沿进纸方向输送。其中，分离组件2的固定辊21位于第一通道板11的背离输送通道110的一侧，由第一通道板11上的通道板开口伸进输送通道110内，固定辊21的轴向沿输送通道110的宽度方向延伸。
浮动辊组件22位于第二通道板12的背离输送通道110的一侧，浮动辊组件22的浮动辊222可由第二通道板12上的通道板开口伸进输送通道110内，浮动辊222的轴向沿输送通道110的宽度方向延伸。
薄片类介质分离机构还包括用于驱动固定辊21和浮动辊222中的至少一个转动的驱动组件4。本实施例中，固定辊21与驱动组件4传动连接，在驱动组件4的驱动下，固定辊21能够绕自身轴线转动。其中，固定辊21与介质之间的摩擦系数μ1大于介质与介质之间的摩擦系数μ0，即μ1＞μ0。浮动辊222也与驱动组件4传动连接，在驱动组件4的驱动下，浮动辊222能够绕自身轴线转动。
调节组件3包括可沿垂直于输送通道110的高度方向移动的调节件31和用于向浮动辊222施加压力的弹性元件34，通过调节件31移动可以调节弹性元件34的变形量，从而调节施加在浮动辊22上的压力。
如图3、图4所示，机架1内设置用于安装浮动辊组件22的安装槽14，安装槽14包括底壁143，底壁143位于输送通道110的一侧；调节组件3还包括定位件32和顶杆33，调节件31与底壁143活动连接，调节件31包括多个沿调节件31移动方向间隔设置的定位部，多个定位部沿输送通道110的高度方向的高度不等；定位件32活动地设置在调节件31与底壁143之间，可沿输送通道 110的高度方向移动，定位件32上设置有与定位部卡接配合的限位部322，顶杆33的第一端穿过定位件32与调节件31连接，顶杆33的第二端与浮动辊组件22抵接，弹性元件34的第一端与顶杆33连接，弹性元件34的第二端与定位件32连接，通过弹性元件34使顶杆33始终抵接在浮动辊组件22上。
安装槽14设置在第二通道板12上，安装槽14的长度沿输送通道110的宽度方向延伸，安装槽14的深度沿输送通道110的高度方向延伸，安装槽14的宽度沿介质输送方向延伸。安装槽14还包括第一壁141和第二壁142，其中，第一壁141和第二壁142沿输送通道110的宽度方向间隔设置，两者均与第二通道板12垂直连接，底壁143垂直地连接在第一壁141和第二壁142之间，位于第二通道板12背离输送通道110的一侧，在第一壁141和第二壁142的内侧分别设置有导向槽145，导向槽145的长度方向沿输送通道110的高度方向延伸，底壁143远离输送通道110的一侧设置两个导向柱144，两个导向柱144沿调节件31的移动方向间隔排布，导向柱144沿输送通道110的高度方向延伸设定长度。
浮动辊组件22还包括支撑架221，其中，支撑架221通过两个插接部223与安装槽14内的两个导向槽145插接配合，插接部223可沿导向槽145的长度方向移动，使支撑架221靠近或者远离输送通道110；浮动辊222设置在支撑架12上，浮动辊222的轴线沿输送通道110的宽度方向延伸，当支撑架221沿输送通道110的高度方向移动时，浮动辊222随之移动，与固定辊21接触或分离。浮动辊222与介质之间的摩擦系数μ2大于介质与介质之间的摩擦系数μ0，小于固定辊21与介质之间的摩擦系数μ1，即μ1＞μ2＞μ0。
机架1还包括盖板15，盖板15与第二通道板12可拆卸连接，用于将浮动辊组件22封装在安装槽14内。在盖板15表面设置有与浮动辊222的位置对应的盖板开口151，浮动辊222穿过盖板开口151进入输送通道110。盖板15上设置有两个带有开口的弹性卡槽152和一个弹性卡爪153，在安装槽14内对应地设置有两个转轴146和一个卡扣147，盖板15的两个弹性卡槽152与安装槽14的两个转轴146卡接，可以绕转轴146轴线转动，封闭或打开安装槽14，当盖板15封闭安装槽时，弹性卡爪153与安装槽14内的卡扣147卡接配合，盖板15相对于第二通道板12的位置固定。
可选地，分离组件2还包括辅助辊23，沿进纸方向，辅助辊23位于固定辊21的上游，辅助辊23与固定辊21位于输送通道110的同一侧。辅助辊23穿过 第一通道板11上的缺口(图中未标出)凸出于第一通道板11上表面设置，可与第一通道板11上放置的介质接触，辅助辊23与驱动组件4传动连接，可绕自身轴线转动，从而驱动与辅助辊23接触的介质沿进纸方向移动。辅助辊23与介质之间的摩擦系数μ3大于介质与介质之间的摩擦系数μ0，即μ3＞μ0。
调节组件3用于调节浮动辊222施加在固定辊21上的压力。如图3至图7所示，调节件31可沿垂直于输送通道110的高度方向移动，比如，调节件31可以沿输送通道110的宽度方向或者输送通道110的长度方向移动。本实施例中，调节件31可沿输送通道110的宽度方向移动。调节件31上设置有与两个导向柱144套接配合的定位槽311，此定位槽311为台阶槽，其中，定位槽311的长度方向沿调节件31的移动方向延伸，此定位槽311的宽度与导向柱144的外径相适配，调节件31的定位槽311与该两个导向柱144套接配合，使调节件31只能沿定位槽311的长度方向移动，需要说明的是，两个导向柱144的排列方向确定了调节件31的移动方向，本实施例中，调节件31沿输送通道110的宽度方向移动，因此两个导向柱144沿输送通道110的宽度方向间隔排布；每个定位部可以是凸部，也可以是凹部；调节件31还包括用于驱动调节件31移动的扳手316。
定位件32包括本体320、连接部321，以及套筒323，其中，连接部321设置在本体320上，用于与导向柱144套接配合，套筒323与本体320固定连接，套筒323的高度沿输送通道110的高度方向延伸，套筒323远离本体320的一端穿过底壁143上的开口延伸至安装槽14内，顶杆33活动地设置在套筒323内且两端分别伸出套筒323。
定位件32的限位部322与连接部321固定连接，用于与调节件31的多个定位部中的任意一个卡接配合，其中，当调节件31的定位部为凸部时，限位部322为凹部，当定位部为凹部时，限位部322为凹部。
本实施例中，调节件31包括沿输送通道110宽度方向间隔设置的第一定位部312和第二定位部313，两个定位部均为凸部，其中，沿输送通道110的高度方向，第一定位部312与第二定位部313的高度差值为d，且第二定位部313比第一定位部312更靠近输送通道110；定位件32的连接部321为两个轴线沿输送通道110的高度方向延伸的通孔，通孔的内径与导向柱144的外径相适配，定位件32通过两个通孔套接在两个导向柱144上，使定位件32只能沿输送通道110的高度方向移动，套筒323沿输送通道110的宽度方向位于两个通孔的 中间，限位部322为凹部。
顶杆33的第一端依次穿过定位件32的套筒323和调节件31的定位槽311，顶杆33的第二端伸进安装槽14内，顶杆33可沿输送通道110的高度方向移动；弹性元件34的第一端与顶杆33连接，弹性元件34的第二端与定位件32连接，在弹性元件34的弹性力的作用下，顶杆33始终抵接在浮动辊组件22上，定位件32始终抵接在调节件31上。本实施例中，弹性元件34为压簧，压簧与顶杆33套接，压簧的第一端抵接在顶杆33的轴肩331上，压簧的第二端抵接在定位件32的套筒323的内壁上。
当使用薄片类介质分离机构分离第一种类型的介质，比如较薄的介质时，调节件31的第一定位部312与定位件32的限位部322配合，顶杆33在弹性元件34的弹性力的作用下抵接在浮动辊组件22的支撑架221上，使浮动辊222以第一压力弹性地按压在固定辊21上。当使用薄片类介质分离机构分离第二种类型的介质，比如较厚的介质时，扳动扳手316，使调节件31的第二定位部313与定位件32的限位部322配合，由于沿输送通道110的高度方向，第二定位部313与第一定位部312高度差为d，第二定位部313比第一定位部312更靠近输送通道110，因此，第二定位部313与限位部322配合使得定位件32向靠近输送通道110的方向移动距离d，定位件32的移动挤压了弹性元件34，使弹性元件34的弹性变形增大，弹性元件34施加在顶杆33上的弹性力增大，因此顶杆33抵接在浮动辊组件22上的压力增大，从而使浮动辊222以第二压力弹性地按压在固定辊21上，第二压力大于第一压力。
可选地，如图3所示，在浮动辊组件22的支撑架221上设置有受力部224，调节件31还包括挂勾315，挂勾315穿过安装槽14的底壁143上的开口伸进安装槽14内部，当移动调节件31时，挂勾315可与浮动辊组件22的支撑架221的受力部224配合或分离，当挂勾315与支撑架221的受力部224配合时，挂勾315可将支撑架221抬起，使浮动辊222与固定辊21分离，此时浮动辊222与固定辊21之间的间距大于两张介质的厚度；当挂勾315与支撑架221的受力部224分离时，在弹性元件34的弹性力的作用下，浮动辊组件22落下，浮动辊222与固定辊21配合。
可选地，调节件31还包括挂钩定位部314，当调节件31的挂勾315抬起浮动辊组件22时，挂钩定位部314与定位件32上的限位部322配合，以固定调节件31的位置。
下面介绍本实施例提供的薄片类介质分离机构的工作过程。
当不需要使用薄片类介质分离机构分离介质时，比如使用薄片类介质分离机构输送折页的介质时，扳动调节件31的扳手316，使调节件31的挂勾315与浮动辊组件22的支撑架221上的受力部224配合，抬起支撑架221，使浮动辊222与固定辊21分离，此时调节件31的挂钩定位部314与定位件32的限位部322配合，使调节件31的位置固定。
当薄片类介质分离机构工作时，根据介质类型调整调节组件3施加在浮动辊222上的压力，对较厚或表面较光滑的介质施加较大的压力，对较薄或表面较粗糙的介质施加较小的压力；驱动组件4驱动固定辊21和辅助辊23沿进纸方向转动，驱动浮动辊222沿退纸方向转动，辅助辊23驱动介质向固定辊21方向移动；当移动至浮动辊222与固定辊21之间的介质是两张时，由于固定辊21、浮动辊222与介质之间的摩擦系数均大于介质与介质之间的摩擦系数，并根据介质的类型调节了调节组件3对浮动辊222施加的压力，因此，固定辊21与介质之间的摩擦力、浮动辊222与介质之间的摩擦力均大于介质与介质之间的摩擦力，固定辊21驱动与其接触的介质沿进纸方向移动，浮动辊222驱动与其接触的介质沿退纸方向移动，从而完成介质分离，实现单张介质的分离；当浮动辊222与固定辊21之间只有一张介质时，由于固定辊21与介质之间的摩擦系数大于浮动辊222与介质之间的摩擦系数，因此在固定辊21和浮动辊222的共同作用下，仍可驱动该张介质沿进纸方向移动。
本实施例提供的薄片类介质分离机构通过设置调节组件，能够根据介质的类型调整施加在浮动辊上的压力，从而能够适应不同类型介质的分离，因此，与相关技术中的薄片类介质分离机构相比，本实施例提供的薄片类介质分离机构的介质适应性强。可选地，本实施例提供的薄片类介质分离机构还能够在不分离介质时抬起浮动辊组件，减少固定辊和浮动辊的磨损。
图8是本实施例提供的另一种薄片类介质分离机构的结构示意图。如图8所示，本实施例中，调节组件3包括可沿垂直于输送通道110的高度方向移动的调节件31、定位件32，以及两个弹性元件34，其中，调节件31与机架(图中未示出)活动地连接，能够沿垂直于输送通道110的高度方向移动，调节件31包括第一楔面；定位件32与机架活动地连接，能够沿输送通道110的高度方向移动，定位件32包括第二楔面，第二楔面与调节件31的第一楔面抵接配合，两个弹性元件34分别位于浮动辊222的轴向两端，每个弹性元件34的第一端 均抵接在浮动辊222的芯轴上，每个弹性元件34的第二端均与定位件32抵接。当沿垂直于输送通道110的高度的第一方向移动调节件31时，调节件31的第一楔面在沿定位件32的第二楔面的表面移动过程中挤压定位件32向靠近输送通道110的方向移动，因此，定位件32挤压弹性元件34，弹性元件34的变形量增大，施加在浮动辊222上的压力变大；当沿垂直于输送通道110的高度的第二方向(其中，第二方向与第一方向相反)移动调节件31时，定位件32在弹性元件34的弹性力的作用下向远离输送通道110的方向移动，此时，弹性元件34的变形量变小，施加在浮动辊222上的压力变小。
图9是使用本实施例提供的薄片类介质分离机构的薄片类介质处理装置的结构示意图；图10是使用本实施例提供的薄片类介质分离机构的薄片类介质处理装置的结构剖面图。如图9、图10所示，本实施例中，薄片类介质处理装置包括分离机构、介质处理机构5、至少一个输送辊组6，以及介质支撑机构，其中，分离机构可以采用上述任意一种分离机构，分离机构的结构形式和工作原理参见上述实施例，此处不再赘述。可选的，分离机构的调节件的扳手316露在装置的外部，因此可不需要拆卸装置即可完成调节组件3的调整。
介质处理机构5设置在分离机构的输送通道110上，沿介质输送方向位于固定辊的下游，介质处理机构5可以是打印机构、扫描机构、读磁机构等处理机构中的一种或几种的组合。本实施例中，介质处理机构5包括第一扫描机构51和第二扫描机构52，第一扫描机构51和第二扫描机构52分别位于输送通道110的两侧，其中，第一扫描机构51安装在第一通道板上，与介质的第一面相对，用于获取介质第一面的图像信息；第二扫描机构52安装在第二通道板上，与介质的第二面相对，用于获取介质的第二面的图像信息。
输送辊组6设置在介质的输送通道110上，用于驱动介质沿输送通道110移动，将介质送至介质处理机构5处，或将完成介质处理操作的介质送至薄片类介质处理装置外部。本实施例中，薄片类介质处理装置包括两个输送辊组6，沿介质输送方向分别设置在介质处理机构5的上游(靠近介质入口的一侧)和下游(靠近介质出口的一侧)，用于将介质送至介质处理机构5处，并将完成介质处理操作的介质送至薄片类介质处理装置外部。
介质支撑机构包括供纸组件7和接纸组件8，其中，供纸组件7设置在输送通道110的入口处，用于放置供批量处理的介质，接纸组件8设置输送通道110的出口处，用于接收完成薄片类介质处理的介质。
本实施例中的薄片类介质处理装置由于使用本实施例提供的薄片类介质分离机构，能够适应不同类型的介质，因此介质适应性强。
于本实施例的描述中，需要理解的是，术语“第一”、“第二”，仅仅用于在描述上加以区分，并没有特殊的含义。
工业实用性
本公开通过将浮动辊组件活动地设置在机架内，使得浮动辊和固定辊之间的相对位置可调，并通过设置调节组件，可根据介质的类型调节施加在浮动辊上的压力，进而调节浮动辊施加在固定辊上的压力，从而能够适应不同类型介质的分离，适应性强。
